WebbIn 5G NR, combination of SS and PBCH (Physical Broadcast Channel) is known as SSB. There two frequency bands supported in 5G NR technology viz. FR1 (Sub-6 GHz) and FR2 (millimeter wave). There are various subcarrier spacing supported in 5G NR viz. 15 KHz, 30 KHz, 60 KHz, 120 KHz and 240 KHz. SSB utilizes subcarrier spacing of 15 or 30 KHz in ... WebbIt describes 5G frame as per NR (New Radio) 3GPP standard. The 5G NR frame structure depicts subframes,slot and symbol configurations. 5G NR Supports two frequency ranges FR1 (Sub 6GHz) and FR2 (millimeter wave range, 24.25 to 52.6 GHz). NR uses flexible subcarrier spacing derived from basic 15 KHz subcarrier spacing used in LTE.
